After I practice or play, I notice that I can hear my voice in my left ear off and on for a while. Similar to having my finger in my ear when I talk. There also feels like there is pressure in my ear. Popping my ears or popping my jaw doesn't resolve the problem. No sinus blockage present. I also notice this when I bicycle for several miles. It seems to be related to the movement of large amounts of air when I breathe for playing sax or biking. I saw an ENT and they found no physical problems. I have had tinnitus for over 5 years. Not sure if this is related. Anyone have any suggestions on the source of this problem?
